BEATER.

Specification of Letters Patent.

Application filed September 17, 1909. Serial No. 518,183.

vand I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawin s, and to the numbers of reference marked thereon, which form a part of this specification.

patent for Beater arms for animal cleaning 'or dehairing machines, filed on the 12th day of June, 1908, Serial No. 438,151, and

v ,in which beater-s or sections of rubber or other belting were, bent centrally and the ends thereof overlapped and bolted to a rotating shaft, the arrangement being such that the axis of curvature ofthe loop extended longitudinally of the shaft. Although such beaters are capable of use for a variety of purposes, one of theirimpon tant uses is'in dehairing carcasses, as, for f nstance, slaughtered hogs.

In operation, said beaters act centrifugally with the rotation of the shaft to strike, beat, and massage the carcasses subjected thereto and upon contact with the carcasses, are first bent back in a direction opposite to the rotation of the Shaft until the looped end passes the carshaft and in consequence such heaters are frequently broken and the life is very much shortened by such recoil.

The object of this invention is to obviate the rebound or recoil of the beater upon .passing the carcasses and to afford a stop adapted to limit the forward movement of the beater approximately to its normal position due to the rotation of the shaft.

It is also an object of the invention to afford a rear stop for the beater acting to prevent short bending of the beater near the Patented June 6,1911.

shaft and to afford a rounded surface over which the beater may be bent without danger of injury.

It is also an object of the invention to afford a construction adapted to limit the for- Ward throw of the beater by reaction and to prevent forward short bending of the beater.

The invention embraces many novel features and consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a view in end elevation of a shaft and beaters secured thereon and equipped with devices embodying my invention. Fig. 2 is a face View thereof.

As shown in the drawings: 1, indicates the shaft, and 2 and 3 respectively the beaters, any desired number of which may be secured on each shaft conveniently in pairs directed oppositely, adjacent pairs of which,

however, may be arranged at any desired angle with each other. Each of said boaters .also secured on said bolts are short, comparatively stiil' sections 15, of belting or other suitable material adapted to reinforce the beater against rearward bending to a point well beyond the shaft. Said bolts also eitend through the iron, steel or other suitable stops 6, each of which comprises a rounded and outwardly and rearwardly curved end 7, at the rear side of the beater with which the same is secured by the shaft, said rounded surface insuring a relatively long bend of the beater when forced rearwardly by contact with that upon which the beater acts. Said plate or member extends obliquely and inwardly beyond the inner end of the beater and at its extremity is provided with aslightly rounded head 8, which contacts the forward side of the other beater of said pair at a point sufiiciently far out on the beater to serve as a positive stop therefor against excessive forward movement.

Curved plates 9, are secured on the forward side of the loop of each beater, the outermost of said plates projectim sufii ciently beyond the loop to guard the send or loop from contacting the carcasses, thereby pbviating excessive wear at the bend of the The operation is as follows: The rapid rotation of the shaft 1, causes the beaters to successively strike the carcasses howsoever supported in the path thereof, said beaters acting centrifugally and also owing to their resiliency acting to resist rearward bending. In passing the carcasses, however, the beaters of necessity are bent rearwardly over the curved face 7, of the stop 6. Any cramping tendency that would otherwise be produced on the bolts 5, being to a considerable extent resisted by the bracing effect of the rounded head or brace 8, -which bears against the complemental beater, thus in eifect, by rigidly connecting the rounded stop 7, with the stop 8, a distinct bracing effect is secured, the cramping effect on the bolts due to-the blow on one beater being in part resisted by said brace and stop 8, which communicates a part, of the shock to the other beater. What is perhaps more important, however, is that having passed the carcasses, the resiliency of the beater a ded by the centrifugal'force due to the rotation of the shaft tends to throw the beaterfforwardly and beyond its normal. position. This is effectually resistedby the stop 8, which is so disposed as to receive and absorb such forward throw thereby greatly extending the life of the beater by preventing the same breaking forwardly.

Of course, though a carcass ever contactany portion of the stop 8, inasmuch as the same curves 'rearwardly, no injury can. be done the carcasses thereby and furthermore, owing to the large space between the shaft and said stop, hair and other refuse can never interfere With the successful operation of the device by lodging in said space.

Of course, details ofthe construction may 1. The combination with shaft of fiexi.

forward side of the complemental heater.

2. The combination with a shaft and flexible looped beaters thereon arranged in oppositely disposed pairs, a curved stop secured at the rear of each beater to limit the rear" ward bending thereof and an integral head connected therewith and extending therefrom into contact with the front face of the other beater of each pair.

3. A machine of the class described embracing a rotutivc shaft, flexible and resilient beaters thereon each provided w i a loop, a curved stop at the rear side of r heater and means bearing against the fr side of each beater and acting to limit ward reaction.

4. The combination with a shaft of'a ble beater secured thereon, a curved a the rear side thereof limiting the ream bending of the same, scraping blades on the outer side of the beater, and a stop'adapted to engage the forward side of said beater at a point somewhat outwardly beyond the rear curved stop therefor.

6. In a device of the class described a shaft, a looped beater secured thereto com prising a strip of flexible and. resilient mate rial folded to provide a loop, means for securing the beater to the shaft, scraping blades secured to the beater, means for preventing rearward short bending of the heater and meahs for limiting the recoil of the beater.
